None of the valve or ignition issues are a big fix, if there's a problem at all. I replaced the cam, t-chain, zeroed cam, valve springs, upgraded ignition to TFI-MSD, water pump, right out of the gate, and really had no big issues with any of it to begin with. However it starts quicker, snappier throttle response, idles smoother, and runs cooler. This weekend job cost around $500 , and I cleaned up a lot of tidbits in the process. Check the 4x4 to make sure it goes in, put it in low range but not for long on dry surface. There shouldn't be any rust issues if its a Carolina truck. A FSJ is a blast to own and drive but they do like attention.
